<p>Sets one property on zero or more objects of a scope.</p>
<p>The first argument determines the scope in which the property is set.
It must be one of the following:</p>
<dl>
<dt><code class="docutils literal notranslate"><span class="pre">GLOBAL</span></code></dt><dd><p>Scope is unique and does not accept a name.</p>
</dd>
<dt><code class="docutils literal notranslate"><span class="pre">DIRECTORY</span></code></dt><dd><p>Scope defaults to the current directory but another directory
(already processed by CMake) may be named by full or relative path.

</dd>
<dt><code class="docutils literal notranslate"><span class="pre">TARGET</span></code></dt><dd><p>Scope may name zero or more existing targets.
See also the <span class="target" id="index-0-command:set_target_properties"></span><a class="reference internal" href="set_target_properties.html#command:set_target_properties" title="set_target_properties"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">set_target_properties()</span></code></a> command.</p>
</dd>
<dt><code class="docutils literal notranslate"><span class="pre">SOURCE</span></code></dt><dd><p>Scope may name zero or more source files.  Note that source
file properties are visible only to targets added in the same
directory (<code class="docutils literal notranslate"><span class="pre">CMakeLists.txt</span></code>).
See also the <span class="target" id="index-0-command:set_source_files_properties"></span><a class="reference internal" href="set_source_files_properties.html#command:set_source_files_properties" title="set_source_files_properties"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">set_source_files_properties()</span></code></a> command.</p>
</dd>
<dt><code class="docutils literal notranslate"><span class="pre">INSTALL</span></code></dt><dd><p>Scope may name zero or more installed file paths.
These are made available to CPack to influence deployment.</p>
<p>Both the property key and value may use generator expressions.
Specific properties may apply to installed files and/or directories.</p>
<p>Path components have to be separated by forward slashes,
must be normalized and are case sensitive.</p>
<p>To reference the installation prefix itself with a relative path use <code class="docutils literal notranslate"><span class="pre">.</span></code>.</p>
<p>Currently installed file properties are only defined for
the WIX generator where the given paths are relative
to the installation prefix.</p>
</dd>
<dt><code class="docutils literal notranslate"><span class="pre">TEST</span></code></dt><dd><p>Scope may name zero or more existing tests.
See also the <span class="target" id="index-0-command:set_tests_properties"></span><a class="reference internal" href="set_tests_properties.html#command:set_tests_properties" title="set_tests_properties"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">set_tests_properties()</span></code></a> command.</p>
</dd>
<dt><code class="docutils literal notranslate"><span class="pre">CACHE</span></code></dt><dd><p>Scope must name zero or more cache existing entries.</p>
</dd>
</dl>
<p>The required <code class="docutils literal notranslate"><span class="pre">PROPERTY</span></code> option is immediately followed by the name of
the property to set.  Remaining arguments are used to compose the
property value in the form of a semicolon-separated list.</p>
<p>If the <code class="docutils literal notranslate"><span class="pre">APPEND</span></code> option is given the list is appended to any existing
property value.  If the <code class="docutils literal notranslate"><span class="pre">APPEND_STRING</span></code> option is given the string is
appended to any existing property value as string, i.e. it results in a
longer string and not a list of strings.  When using <code class="docutils literal notranslate"><span class="pre">APPEND</span></code> or
<code class="docutils literal notranslate"><span class="pre">APPEND_STRING</span></code> with a property defined to support <code class="docutils literal notranslate"><span class="pre">INHERITED</span></code>
behavior (see <span class="target" id="index-0-command:define_property"></span><a class="reference internal" href="define_property.html#command:define_property" title="define_property"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">define_property()</span></code></a>), no inheriting occurs when
finding the initial value to append to.  If the property is not already
directly set in the nominated scope, the command will behave as though
<code class="docutils literal notranslate"><span class="pre">APPEND</span></code> or <code class="docutils literal notranslate"><span class="pre">APPEND_STRING</span></code> had not been given.</p>

in each scope.</p>
